hi,
i am new to this options....
can any one explain ....
how to read the table and explain how to benefit from this?
Hi Swamy, Your question is very foundation of understanding real action in option market so I am trying my best to keep it as simple as possible. Hope this helps other newbies as well..
--------
To trade in options, we need to have following information with us
a) Underlying Security
b) Option Type - CALL or PUT
c) Contract Expiry
d) Strike price
Once you have all above information, you have unique identifier of the option contract that you can buy or sell in the market.
The table below can be logically divided in two parts. Left part of table has information related to CALL options and right part of table has information about PUT options.
In the center, we have various strike prices for option contract arranged in ascending order.
Expiry Date - This is the option contract's expiry date. Currently there are options of February-2010, March-2010 and April-2010 month are traded in the market.
Open Interest - Number of open positions for a particular strike price.
LTP = Last traded price
Net Change - % change in the price at which a particular option is traded in market last, with respect to the closing price of previous trading day.
Volume - Number of contracts traded today
Bid Quantity - Quantity given in the last open buy order for this particular strike price.
Bid Price - Price given in the last open buy order for this particular strike price.
Offer Price - Price given in the last open Sell order for this particular strike price.
Offer Quantity - Quantity given in the last open Sell order for this particular strike price.
You might notice that part of the table has cells with coloured background. These cells indicate that those particular strikes are In-The-Money. The cells with white background are for Out- of The-Money strikes.
Lets take and example and try to find the latest quote from the table. Lets say we want to Buy, Tatasteel PUT, Strike 500, Feb-10 expiry,
So you ensure that you are looking at option chain of February-10 expiry.
Then go to the row strike related to strike price = 500. As you are interested in PUT, so pay attention to the numbers on the right part of the table in this row.
We see bid quantity of 764 and bid price 10.35. I.e. someone is standing in the queue to buy the put at 10.35. So if we are a seller, then we will get this price for our market order. If we are placing market order to buy then we might have to pay more then 10.35.
Number in next 2 columns tells us that someone is ready to sell 764 quantities at 10.95. So if we are placing market buy order, then it will be filled at 10.95. Or if we are selling through market order then we might get a price less then 10.95.
Remaining info on this row is more for information purpose telling you that there are 172 contracts traded today, the price has fallen by 0.5% from yesterday's price. The last trade took place at 10.90 and as of now, 183360 is the open interest (OI). As the lot size for Tatasteel is 764, this OI results in 183360/764 = 240 contracts.
Hope this helps.
Happy Trading
